上一个版本设置的是20分钟连接没有活动就会移除，新版本已去除，可以下最新的发布包试试

怎么更新后 感觉不好使了呢？
git pull origin master
mvn clean package
cd distribution/proxys-server-0.1/
bin/stop.sh
bin/startup.sh
# 客户端一样的操作
等全部更新完后 反而内网穿透不灵了呢？

把之前的清理下重新启动，如果还有问题把server和client的启动日志发出来看看

但是怎么清理呢？ 我试了下面的方案 都不行
-
mvn clean 【单单clean】
-
rm -rf distribution && mvn clean 【删除distribution包后 再clean】
-
rm -rf lanproxy && rm -f ~/.lanproxy/config.json && git clone XXX 【删除已下载的lanproxy包 重新clone 同时删除已配置的客户端连接】
运行了一段时间后 （大概一个小时多） proxy server 就有下面的错误

另外虽然proxy-server 和 proxy-clients的进程都在 但是管理界面上status都是Down的状态。
反正这个问题是升级后 才开始有的 不确定是代码的问题 还是 我的网络的问题 如 外网ip变化会有影响吗？ 因为我看server.log中有好几个外网地址
R:/211.157.XXX.XX:15848
R:/60.205.XXX.XX:64952
R:/140.205.XXX.XXX:55054
proxy-client 刚连接上的时候 都是211这个地址 但是后面也发现有很多60的地址以及一个140的地址

客户端和服务器用最新的代码，可以直接下载最新的发布包，再就是使用ssl 端口连接，不用明文端口
另外看看你用的mongodb客户端连接池有没有配置发送心跳包的功能，网络连接一个小时没有任何数据传输基本上已经被运营商中间路由移除了

mongo有没有发送心跳包 我不确定 但是mysql肯定有
spring.datasource.test-while-idle=true
spring.datasource.time-between-eviction-runs-millis=30000
spring.datasource.validation-query=select 1
那为什么mysql所在的proxy client机器也是Down的状态呢？ 并且mongo和tomcat的client.log都没有异常日志 单单mysql 的client.log有异常日志呢？（相隔了有8个小时多）

今天上午更新代码后 又观察了一天 好像恢复正常了 如 mongo shell连上后 若长时间没有操作 能够自动恢复连接 如下所示
> show collections

mysql也一样
mysql> select version();
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...

但是服务端仍发现了一些异常日志 虽然不影响功能

我这边没做什么 就是新开了一个终端 mongo shell 和 mysql client都连上了而已

TooLongFrameException 这个异常是正常的，不用管，是有人用浏览器访问了proxyserver的端口
